The modular construction of the AVS 270 allows the fast and easy exchange of system components. The AVS 270 allows the usage of both detection systems (optical and thermical).

In spite of the high sample throughput, the AVSPro II provides maximum accuracy and reproducibility. Furthermore, working with the AVSPro II is easy and even allows unsupervised 24-hour operation. Particularly with time consuming measurement runs, the AVSPro II helps to substantially reduce the burden on qualified employees. An additional advantage is the increased level of safety when handling aggressive media, e.g. sulphuric acid, which is achieved through the fully automatic measurement procedure. The ProClean system and the micro dosing make routine operation safer. The filtration of solutions, which occasionally may be harmful, can thereby be ommitted. The capacitive sensors in the suction pipe effectively prevent any damage of the measuring system.

In practice, this means that it is not only possible to simultaneously test the characteristics of samples with greatly differing viscosity, but also to perform measurements in various different capillary sizes and types of viscometers. This even applies to a combination of optical and thermal scanning. Therefore, preliminary sorting of the samples with regard to viscosity and the size of capillary required for the testing process is no longer necessary. It is possible to “individually” allocate each sample to a capillary viscometer that is currently being used by means of the conventional MS-Windows® “drag and drop” method. This procedure makes it possible to increase the sample throughput. AVS P The allocation between the sample and the viscometer is shown on the status display. … easy, reliable and safe The proved and tested AVSPro II software also makes it possible to prepare additional individually selected calculations, such as: - mean value, - standard deviation, - outlier test (A %), - Hagenbach correction, - absolute viscosity, dynamic viscosity (density value required), - viscosity index (measurement at two temperatures required), - SUS and SFS, - relative viscosity, - specific viscosity, - reduced viscosity (viscosity number), - inherent viscosity and - K-value.

They can be used for both manual measurements and, when used in connection with viscosity measuring equipment, for automatic measurements. The most important characteristics of the transparent thermostats are their ability to maintain a constant temperature and capability of visual observation of the flow of the fluid in the viscometer. The transparent thermostats of the series CT 53 and CT 54 are suitable for viscosity measurements in compliance with DIN 51 562 (Part 1) and ASTMD 445. They are comprised of a stainless steel bath with insulating glass, a coated steel casing and a bath thermostat. In addition, the CT 54 has an integrated discharge outlet on one side to drain the bath. An RS-232-C interface enables it to be connected to a PC. The viscosity of Newtonian liquids is extremely dependent on temperature. Depending on the measurement medium, a deviation of 0.5 to 2% can be expected for a temperature deviation CT 52 of 0.1 K. For this reason, the significant influence of temperature on the viscosity of a fluid must be taken into consideration when selecting a thermostat. All SCHOTT Instruments thermostats have the possible temperature stability of 0.01 K (see Technical Specifications) under optimum ambient conditions. 194 CT 52 The transparent thermostat CT 52 is made of acrylic glass and it is able to take up to two automatic measurement positions or brackets for manual measurements. Due to its design its ability to keep the temperature constant is not quite as great and it can only be used up to temperatures of +60 °C. If temperature constancy is not a top priority, the CT 52 is a cost-effective alternative. CT 53 This thermostat is for use with temperatures between +5 °C and +102 °C. Between +5 °C and +50 °C cooling is recommended to maintain the temperature constancy. Either a flowthrough cooler (e.g. CK 300, see Accessories) or simple cooling with circulated water can be used.

The main differences are the number of measuring positions (the number doubles) and the additional discharge outlet to drain the bath. Up to 8 micro-TC-viscometers can be positioned in the thermostats if 2 special VZ 7191 holders are used.

This can be achieved either by using circulated water or a flow-through cooler (e.g. CK300). * When using with 4 or 8 micro-TC-viscometers, a special holder (Type: VZ 7191) is required for two of the existing measurement positions. ** When using at very low temperatures (well below room temperature) a cryostat is required. Cryostats can be included in delivery (at the list price of the manufacturer). 196 Accessories The flow-through cooler is available for Flow-through cooler CK300 The fluor-hydro-carbon gas free flowthrough cooler serves to mechanically cool the bathfluid and is filled with environment compatible coolant R 134a.
